Course Introduction:There are two types of selection sorting: simple selection sorting and heap sorting. Simple selection sorting is an intuitive sorting algorithm, while heap sorting generates a maximum heap from an unordered sequence, and swaps the positions of the top element of the heap with the last element. Generate a maximum heap with the remaining elements, exchange elements sequentially, and generate a maximum heap.

Course Introduction:In Python, you can sort a list using the selection sort algorithm. The basic idea of selection sort is to select the smallest (or largest) element from the unsorted part each time, and then put it at the end of the sorted part.

Course Introduction:1. Introduction Primary sorting algorithms refer to several relatively basic and easy-to-understand sorting algorithms. There are three primary sorting algorithms: insertion sort, selection sort and bubble sort. Although their efficiency is lower than that of advanced sorting algorithms, after understanding the primary sorting algorithm, it will be much easier to learn the relatively complex advanced sorting algorithm. 2. Description Selection sorting means selecting the smallest or largest data from an unordered array each time, and putting it from the unordered array to the end of the ordered array to achieve the sorting effect. The average time complexity of selection sort is O(n2), and the time complexity in the best case and the time complexity in the worst case are both O(n2). Additionally, it is an unstable sorting algorithm. The selection sort process is easy to understand. As shown in Figure 2-4

Course Introduction:How to do selection sort using Python Selection sort is a simple but less efficient sorting algorithm. Its basic idea is to select the smallest (or largest) element from the data to be sorted each time and place it at the end of the sorted sequence. Repeat this process multiple times until all data is sorted. The following will introduce in detail how to use Python for selection sorting, and provide specific code examples. First, define a selection sort function, named selection_sort, which accepts a list to be sorted as

Course Introduction:Simple selection sort is an intuitive sorting algorithm. In an unsorted sequence, the smallest element is selected and exchanged with the first element of the sequence, and then the smallest element is selected from the remaining unsorted sequence and exchanged with the second element of the sequence. Bit elements are exchanged, and so on, finally forming a sorted sequence from small to large.
